State Rank Reason (see State Rank above)
DRAFT: Requesting feedback on the 2026 revised rank, factors, and State Rank Reason outlined below and in the Conservation Status Rank Report.
Clintonia uniflora is common and widespread in mesic, forested habitats of western Montana. While statewide population numbers are unknown, they are believed to be robust and well above minimum levels needed to maintain the species' viability in the state. No significant and widespread threats to the species are known.
